DESCRIPTION
The CAS + FSK IC Calling Number Identification Receiver IC with Calling Waiting is a CMOS integrated circuit,
which provides an interface to various calling information delivery services such as Calling Number Delivery
(CND), Calling Name Delivery (CNAM) and Calling Identity on Call Waiting (CIDCW) compatible with the
Bellcore GR-30-CORE, British Telecom Calling Line Identification Service (CLIP), the Cable Communications
Association's Caller Display Services (CDS). The device also contains a power down circuit, a ring detect
circuit, a carrier detect circuit, a synchronous receive data and clock output, 8051 like host interface for easier
system implementation.
